Intrathyroid parathyroid adenoma: report of two cases and literature review

Abstract

Approximately 80% of patients with primary hyperparathyroidism have a parathyroid adenoma, with surgery being the only definitive treatment. Sometimes in surgery there is difficulty in identifying the pathological parathyroid gland at which time the possibility of ectopic parathyroid should be considered. We present two cases of patients which after hemithyroidectomy histopathological report, reported intrathyroid parathyroid adenoma. Intrathyroid parathyroid adenomas are an infrequent presentation of parathyroid adenomas that require high clinical suspicion if they are not detected by imaging studies in the preoperative period.
